Taipei Public Bike-Sharing System, or Youbike, has grown dramatically and become the major green vehicles for short-distance transit and recreation in the city since its launch in 2009. In the meantime, Taipei City is also suffering from the increasing number of bicycle accidents and casualties. In this research we examined the spatio-temporal co-occurrence patterns of Youbike usages and bicycle accidents in the city to discover the association between them. Using spatial autocorrelation methods and kernel density estimations, we first identified the clusters and overlapping hotspots of Youbike stations and bicycle accidents, and furthermore, different bike usage patterns filtered by number of rentals, average bike speed, possible cycling routes, and time periods were introduced to identify the high risk time and areas of bicycle accident occurrence.
